Featured Image Zoom Plugin
Add a [zoom] shortcode to display a zoomable featured image.
Add the [zoom] shortcode to a page, post or custom post-type post. If the post has a featured image it will displayed on the page, and when you move the cursor over the image, the image will be magnified with the image viewport remains constrained to the dimensions of the original image.
on a mobile/touch device the image will also be zoomable, but as there is no hover state this is achieved by means of a pinch & zoom action.
On my site you can see a demo of the plugin.
Usage:
Ensure that your post/page has a featured image defined.
Use a [zoom] shortcode to your page.
Some optional shortcode parameters can also be used.
=size=
The large image is used by default for the unzoomed image. Use the size parameter to use a different defined image size.
eg ‘[zoom size=thumbnail]’
=zoomsize=
The full image is used for the zoomed overlay. This can be changed using the zoomsize shortcode parameter.
eg ‘[zoom zoomsize=large]’
The image size definitions used for the the unzoomed and zoomed images should have the same aspect ratio and cropping.
=zoomin=
This can be used to tweak the level of zoom. The value must be a positive integer. The default is 6 so if the zoom level results in too much magnification on hover, try a lower value.
eg ‘[zoom zoomin=2]’
Installation
- Upload the plugin folder to your ‘/wp-content/plugins/’ directory
- Activate the plugin through the ‘Plugins’ menu in WordPress

FAQ
There isn’t one. This is a lightweight plugin with no options apart from the shortcode parameters so there is no need for an admin page.
You can call the shortcode within the template:
echo do_shortcode( '[zoom]' ); Or you can directly use the shortcode’s function, passing an empty value for the parameter values to use the defaults. You can confirm that the plugin is active by first checking that the function exists:
if ( function_exists('cc_zoom_featured_image') ) { echo cc_zoom_featured_image(''); } To use this with different values for any of the parameters, the parameter/value can be included in an array:
echo cc_zoom_featured_image( array( 'zoomin' => '2') ); You can make a donation via my donation page
I would also appreciate a review on the plugin review page if you enjoy the plugin.
If it isn’t working for you, please refer to the documentation and existing posts on the plugin’s forum. If the existing answers do not address your issue, please post a question on the plugin support forum. If you have problems and leave a negative review before asking for support, that is very unhelpful and actually tells people more about you than about the plugin. Please don’t be that guy.
